The Repubblica Roma web site is reporting about a project carried out by teachers and students at the Leopoldo Pirelli industrial high school in Rome in which students have built cold fusion cells which according to one of the instructors involved have achieved excess heat levels of 400 per cent.

400 per cent of what? Doesn't anybody proofread before posting anymore?

Well, this thing is stoked with hot water and allegedly makes the water even hotter, producing a weak wet steam. Maybe they are claiming heat content of the water charge with respect to room temperature. Heat the hot water with 100 Joules, pour it in, and out comes 400 Joules in steam and hot water or something like that. But this ought to be spelled out, not left to guess.

Do they mean

"Output = 5X Input"

?

It’s not a proof read problem. It’s the terminology in LENR. Every science has its own language. In LENR the input is chemical energy and the output is “unknown” but presumably nuclear fusion occurring at low energy levels. So outputs are often quoted from 4 to 20 times the inputs, or COP 4-20.
